KV2 Audio SL2.15 - Manual (Page 4)

Thank you for purchasing this KV2 Audio, SL series system, consisting of the SL3000 stereo controller/amplifier
unit, two SL412 speakers and optional variants of subwoofers.
The new SL412 and SL2.15 speakers incorporate an eye catching, slim, stylish cabinet design. Designed to
integrate either externally through simple wall mounting, suspension, ground stacking, or internally into walls
and surfaces. These units can be designed and supplied with custom colors, grill templates and logos, offering
a flexible and true designer integration product. Using KV2 Super Live Audio technology, the SL412 loudspea-
ker utilizes 4 x 12” low mid-range components and the proven and highly respected horn assembly from the
VHD1.0 with a single 8” mid-range and 3” large format NPVD compression driver. This mid-high horn has an
extremely coherent-wide horizontal dispersion of over 110 degrees whilst the purpose designed 4 x 12” confi-
guration dramatically reduces the most common problem of immediate reflections within the 300÷800Hz
range usually associated with wide dispersion loudspeakers. The end result is a full and wide sound propagati-
on exactly where it is required. Whilst the SL412 can be utilized with any of KV2’s wide range of sub woofer
systems depending on the actual application, the accompanying SL2.15 utilizes the same slim line design to
allow for an aesthetically pleasing and acoustically punchy system that can virtually disappear against a wall.
The SL2.15 incorporates 2 x 15” speakers in a specially designed shallow cabinet to output maximum bass
response.
The SL412i & SL2.15i are exact identical performance and finish units of the existing SL412 & SL2.15, except they
do not incorporate the fixed handles for touring and presentation use.
The ‘I’ version is designated for fixed installation use with the same existing mounting and flyware fixings.
This manual contains important information on operating the SL system correctly and safely. Please take some
time and read this manual to familiarize yourself with the advanced features of this system.
The SL3000 Amplifier is a three-way, active control and amplification systems, specifically designed for the KV2
Audio SL series loudspeaker systems. It houses all signal processing and amplification as well as providing
control for external subwoofer cabinets configurations, and to operate additional subwoofer cabinets if
needed. External subwoofers are powered by the external subwoofer amplifier (VHD3200).
The amplifier compliment and configuration inside the SL3000 Amplifier is as follows:
High Frequency - 100-watt, Class AB, Push pull, Low intermodulation design.
Mid Frequency - 200-watt, Class AB, Push pull, Low intermodulation design.
Low Frequency - 1000-watt, High-efficiency, Current-enhancing switch mode technology with Linear Active Filter.
In most cases it would be advisable to use a KV2 Audio Line driver (LD4) in addition at the mixer end to ensure
that the line to the amplifier is driven correctly and the signal integrity maintained.
Although this system is simple to operate, improper use can be dangerous. This is a very high-powered device
that can put out high voltages and sizeable currents. Always use safe operating techniques with the SL series
system.
